Abstract

The mechanical properties of silica alcogels and aerogels were measured by the three-point bending technique. Elastic moduli and the fracture strength were investigated as a function of concentration of silicon compound, catalysis conditions, and aging time. The evolution of modulus and strength was followed during gel to glass transformation. Toughness and fracture energy results of aerogels are presented.
